You can see on Rail Planner app that there's a 26 min walk from Termini to Tiburtina. To avoid that, take the subway (Line to Tiburtina.

It is a regional train, fully included and no extra cost.

I don't know this exact train but if you show up enough in advance, you're guaranteed to have seats. Nobody can have seat reservations anyway.

1. Please don't use the rail planner app to plan. It's unreliable, so what it says is irrelevant.
2. If you do use it, please make sure you have the latest update. My app shows this train as leaving from Roma Tiburtina at 11:11.
3. From Roma Termini, you can indeed use Metro B. The metro is not included in the pass.
4. The only included train you could use to connect from Roma Termini is the one leaving at 10:05.
5. Reservations are not possible for this train to Firenze, but you'll be OK.

Are you sure that it leaves Tiburtina at 10:35 ? Both Trenitalia and DB show it leaving at 11:11.

Oops, my bad, it's 11:11 indeed. Edited my post.

10:35 is what Trenitalia indicates from Roma Termini. I doubt if that's a real timetable though.

Thank you

Can you tell me the apps to use in Netherlands & Denmark to find train details, like timings and platform etc. I have already bought the reservations etc

As a general rule if you have a confirmed reservation that will be the time and station of departure. It will also show the train number - very important.

There are many planners that you can check with but I would advise the dbahn and OBB offers for checking, but the only “definitive” source will be the operators own site, which will show planned changes.

Always check that the train number is the same as your reservation.

Netherlands: NS app (look for blue arrow on a yellow background as logo)

Denmark: DSB app (red background, white DSB letters in a hexagon)
